I see that you haven’t opened a support topic asking for assistance.
I am unable to replicate this on GT Metrix or Google Page Speed Insights and I have the same score when Wordfence is active or inactive. Posting in the support forum for help would give us a chance to look and see what the problem is, help you fix it, and provide a solution that others that run into this issue will be able to find in a search and solve without getting frustrated like you did. We cannot help in the review section where you posted as forum rules prevent us from offering support here.
